`tom of the mold in order to rivet into cheese is as follows.

without bending and is similar to the bottom plate I8.

' It will be noted from Figs. 2 and 3 that the four side walls of themold are perforated by vertical slots 24 and 25 through said side wallsfrom a point 25 which is usually several inches from the top 27 of themold, and extend downward to the top of the bottom plates 'I and II. Thepurpose of these slots will'be explained below.

In Fig, 4 are shown two molds 28, Z9 which are laid on their sides in ahorizontal position, and are provided with the top and bottom plates 30,3|, 32, 33 respectively. The molds 28 and 29 are joined in this instanceby a metal open `ended shell 34, the one end of which enters the mold 29and engages against the plate 32 of said mold, and the opposite end ofsaid shell encloses the bottom 35 of the mold 28.

of metal shell separators 34, 34 etc. 36 represents the head of apressure jack, which engages against the top plate 33 of the mold 28,and it is also seen that the head of ka pressure jack may be inserted inthe aperture 49 ofthe mold 29, and pressure exerted from'both ends ofthe series of molds, and the curd which is Aplaced in said molds may besimultaneously pressed or matted in each mold of the series.

In the Figs. 5 and 6 vof the drawing is shown a modified type of moldwhich is -made of metal but very similar to the type above described,which is rmade of wood. In these figures it will be noted that the sidewalls 37 and 38 are made integral, the corner 39 being merely bent intoproper shape. Similarly the side walls 40, 4I are made from a singlebent metal plate.. The two plates 38 and 4| are shown joined at thecorner by a slip joint in which an extension 42'of the plate 4| passesthrough an aperture made in an ex- Two or more of these slip joints maybe made in thevertical height of the plates 38 and il as readilyunderstood. It is seen that this is an alternative means of -securingthe effect of ya hinge joint at this particular corner of the mold.

vThe plates 37v and i0 may be bent in theform shown at the cornerli lofthe mold and a bolt passedthrough the two extensions with a nut thereonforming a means of locking the said plates together at this corner ofthe mold.` The bottom l5 of this type of mold is similar to the bottomof the first described mold having` an aperture 46 therethrough but inthis case the edges may be turned up at 4I and 43 around the botthebottom 45 to the side walls of the mold if necessary.

The procedure which I follow in making curd Curd is placed in the moldto a proper height therein for the amount of cheese rwhich it is desiredto make at any particular pressing. The amount necessary to produceacertain number of pounds vof cheese is the false sides I9, 20, 2|, 22 0fthe mold.

l When the curd has matted and the'material stiffened to a properdegree, the'corner' of the It is seen that any rnumber ofmolds may bejoined in this fashion using a series,

mold I 4 is opened slightly, enough to permit the removal of the plates23 and I9 to 22 inclusive. A wire is next placed through the top of theslots 24, 25 etc. near the top of the mold and same is extended acrossthe mold from the exterior of the walls 5 and 9 and 6 and I Il, and isforced down through the cheese to the bottom plate I2. This cuts thecheese into proper vertical divisions in two directions. These sizes areof course made to correspond to the desired Weights of cheese to bepackaged. After the vertical cuts have been made either by a wire orknife inserted in the slots just described, the jack acting against thefalse bottom I8 is advanced upwardly and raises the contents of the moldto a certain height (which is 1% inches in thickness usually for a yonepound size of cheese) above the top of the mold. A wire is thenpulledacross the top of the mold horizontally cutting olf a layer offinished cheese into the desired one-half or one pound sizes. It is seenthat where the side walls of the mold are made of resilient material,that it may be unnecessary to have a hinge at the corner 4 of the moldas by opening the corner slightly at I4 the side walls may besprungsufficiently to permit removal of the false side plates I9 to 22inclusive.

Attention has been called in this specification as to the methodfollowed in pressing the contents of a series of molds as shown in Fig.4 of the drawing.

After the cutting operation into cheese of the desired weight,particularly one-half and one pound sizes ordinarily used in the trade,they are wrapped in tin foil of a properl size, and the tin foil isfused on to the sides of the cheese by passing it lightly over a heatedsurface on all sides of the cheese, This has the effect of causing thetin foil to adhere Very closely to the cheese, and preventsrind fromforming on the outer surfaces of the cheese, and also prevents thedrying out of the cheese. The cheese may also be wrapped in waxed paper,or waxapplied to the exterior of the cheese if desired. This method ofpreparing cheese reduces losses to the retailer, by` eliminating thedryingfout of the cheese by air exposure, and obviates the necessity ofcutting off rind which forms on the exterior surface of the cheese, bythe retailer as unsaleable; and the cheese is also prevented frombecoming undesirable and harsh to taste, because the tin foil is in suchclose proximity to the material that no deterioration can take place.

The advantages of this method are apparent in that a quantity of curdfrom thirty, to'one hundred and ve pounds approximately is weighed intoa mold at one time for pressing and shaping into finished sizes, havinga required Weight. No cotton is used, and there are Vno mechanicallosses in bandaging or dressing, no rind is formed on the cheese, andthe labor is lessened in that a large number of cheeses are made and cutat a single operation, thereby eliminating much of the labor which hasto be performed when individual molds are used for each one-half or onepoundsize of material.

I claimf- 1. In a mold for making cheese, an open-ended box-like moldAcomprising two similar parts, hingedly connected at one corner of themold, and lockingly connected at the diagonally opposite corner of themold, a pair of side walls on each part of the mold rigidly connected toeach other, a rigidly mounted triangular bottom for second rigidlymounted triangular bottom for the other part of the mold having a recesstherein, adapted to cooperate with the first-named recess, and form asingle central opening in the base of the mold for admitting the headofa pressure jack therethrough, a removable false bottom plate, withinthe mold, a removable and slidably mounted side plate on each side ofthe interior of said mold, and a top plate adapted to slidably operatewithin the removable side plates for compressing curd` used in makingcheese, when pressure is applied to the top andv false bottom plates ofthe mold.

2. In a mold for making cheese into predetermined small parcels as tosize and weight, an open-ended box-like mold comprising twocomplementary parts, hingedly connected at one corner of the mold, andlockingly connected at a diagonally opposite corner of the mold, a sideand an end wall rigidly connected together on each part of the mold;each pair of side 'and end walls respectively; having oppositelypositioned vertical slots therein, adapted to receive a transversehorizontal wire therethrough, for cutting the cheese into `verticalmasses of proper size, a triangular bottom for one half of the mold,mounted on the side walls thereof, and having a recess therein, a secondtriangular bottom for the other half of the mold, having a recesstherein, adapted to co-operate with the rst named recess, and form asingle central opening in the base of the mold for receiving the head ofa pressure jack, a removable false bottom plate within the mold, aplurality of removable side plates slidably mounted within the mold,each in proximity to one of the sides of the mold, and a topvplateadapted to slidably operate within the removable side plates, for theIpurpose of compressing the curd used to make the cheese, when pressureis applied to the said top plate of the mold.

3. In the means for pressing curd into cheese, a number of box-likeopen-ended molds in alignment with each other, a slidable top plate ineach mold, a hollow metal shell between each pair of molds, each havinga flanged recess at one end adapted to receive the bottom end of a mold,and an extension of reduced size adapted to enter the open end of anadjacent mold and engage against the slidable top plate of said mold inorder to compress the contents thereof When pressure is exerted on thecontents of the end molds of the series.
